[0002] Hot extruded aluminum alloy profiles vary in thickness, and during the cooling process, they are prone to wave deformation due to uneven cooling temperature. Especially for aluminum profiles with thick ends, large waves are more difficult to control.

[0003] For profiles that are too thick at both ends, they are affected by the uneven cooling temperature during the cooling process. Wave deformation will appear in the middle of the profile surface after cooling, making it impossible for customers to use it, which seriously affects the appearance of the profile.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0034] like Figure 1 As shown, a method for adding back ribs to a profile to prevent cooling waves in one embodiment of the present invention comprises the following steps:

[0035] S1, obtaining the size specifications of the profile to be produced and processed, and determining whether the profile will cause wave deformation due to uneven cooling during the cooling process.

[0036] Generally speaking, after obtaining the size specifications of the profiles that the customer needs to produce and process, the preset correlation coefficient function is used to calculate the correlation coefficient between the profile to be produced and processed and multiple pre-stored cooling wave profiles that will cause wave deformation due to uneven cooling during the cooling process. Based on the correlation coefficient, it is determined whether the profile will cause wave deformation due to uneven cooling during the cooling process.

[0037] Specifically, the preset correlation coefficient function Among them, x i Indicates the i-th dimension specification attribute value of the profile to be produced and processed, y i represents the i-th dimension specification attribute value of the cooling wave profile, n represents the number of dimension specification attribute values, and RF represents the correlation coefficient. The dimension specification attribute values ​​include but are not limited to the thickness values ​​at both ends of the profile, the length value of the profile decorative surface, the width value of the profile decorative surface, the wall thickness of the profile, the cross-sectional dimensions, the bearing capacity, etc. If the correlation coefficient RF between the profile to be produced and processed and one of the pre-stored cooling wave profiles that will cause wave deformation due to uneven cooling during the cooling process is greater than the preset coefficient threshold, it is determined that the profile will cause wave deformation due to uneven cooling during the cooling process.

[0038] In this way, during the profile design stage, it can be determined whether the profile to be produced and processed will cause wave deformation due to uneven cooling during the cooling process, which facilitates the subsequent optimization of the profile cross-sectional structure.

[0039] In addition, in the prior art, the plurality of cooling wave profiles pre-stored in the database which will cause wave deformation due to uneven cooling during the cooling process are often standard profiles. If customers customize non-standard profiles, it is often impossible to determine whether they will cause wave deformation due to uneven cooling based on the required size specifications before production. The factory workshop needs to use mold samples to determine whether the customized non-standard profiles will cause wave deformation due to uneven cooling during the cooling process, which is time-consuming, labor-intensive and wastes resources.

[0040] Compared with the existing technology, the preset correlation coefficient function can provide a new reference and judgment idea for determining whether non-standard profiles will cause wave deformation due to uneven cooling during the cooling process, which can improve production efficiency and save production resource costs.

[0041] S2, if yes, optimize the cross-sectional structure of the profile by setting back ribs inside the profile to offset the wave deformation caused by uneven cooling.

[0042] Specifically, the cross-sectional structure of the profile can be optimized by providing back ribs inside the profile and on the back side of the decorative surface generating the waves, thereby offsetting the wave deformation caused by uneven cooling.

[0043] As for the shape and size of the back reinforcement, the method for obtaining it specifically includes the following steps: first, obtain a plurality of cooling corrugated profiles pre-stored in the database which will cause wave deformation due to uneven cooling during the cooling process, and then obtain the back reinforcement shape and size of each cooling corrugated profile corresponding to the qualified profile which meets the customer's tolerance requirements and production conditions by setting back reinforcement inside the profile to optimize the profile cross-sectional structure and offset the wave deformation caused by uneven cooling; finally, the back reinforcement shape and size of the qualified profile corresponding to the cooling corrugated profile under the maximum correlation coefficient is used as the initial shape and size of the back reinforcement of the profile to be produced and processed.

[0044] The initial back reinforcement shape and size of the profile to be produced and processed is obtained, and the mold sample can be used to check whether the initial back reinforcement shape and size can optimize the cross-sectional structure of the profile to be produced and processed to prevent the occurrence of cooling wave deformation. If so, the initial back reinforcement shape and size are used as the final back reinforcement shape and size; otherwise, the back reinforcement shape and size of the qualified profile corresponding to the cooling wave profile under the second largest correlation coefficient are updated and used as the initial back reinforcement shape and size of the profile to be produced and processed, and the mold sample is opened until the initial back reinforcement shape and size can optimize the cross-sectional structure of the profile to be produced and processed to prevent the occurrence of cooling wave deformation.

[0045] The above method is used to determine the initial back reinforcement shape and size of the profile to be produced and processed. First, the back reinforcement shape and size of the qualified profile corresponding to the cooling wave profile under the large correlation coefficient is considered. The back reinforcement that can optimize the cross-sectional structure of the profile to be produced and processed can be quickly and accurately set to prevent the back reinforcement generated by the cooling wave deformation on the profile surface. It can reduce the number of mold opening samples to a certain extent, further improve production efficiency, save production resource costs, and also provide a new reference judgment idea for the design of the back reinforcement shape and size.

[0046] To summarize, in the method of adding back ribs to the profile to prevent cooling waves, first determine whether the profile will cause wave deformation due to uneven cooling during the cooling process based on the size specifications of the profile to be produced and processed. After determining that the profile to be produced and processed will cause wave deformation due to uneven cooling during the cooling process, back ribs are set inside the profile to optimize the cross-sectional structure of the profile to offset the wave deformation caused by uneven cooling. In this way, before the production of the profile to be produced and processed, the cross-sectional structure of the profile is optimized by setting back ribs, which can avoid the wave deformation of the profile after cooling, and solves the problem that the profile is affected by the uneven cooling temperature during the cooling process, and the middle of the surface will have wave deformation after cooling, which makes it impossible for customers to use it and seriously affects the appearance of the profile.

[0047] As a preferred technical solution, the two ends of the profile are solid structures, the middle of the profile is a hollow structure and the outer side is a decorative surface, the back ribs are arranged on the inner side of the profile, the profile is an aluminum alloy profile, the thickness range of the two ends is 40mm-45mm, and the width range is 300mm-350mm.

[0048] The back rib is a boss and is arranged along the length direction of the profile and located at the center of the inner side. The height range of the boss is The width of the boss can be set according to the cross-sectional width of the profile, and the span range is 5mm-15mm, wherein THK represents the wall thickness of the profile.

[0049] Preferably, the height of the boss is at least 2 / 3 of the wall thickness.

[0050] In the profile, since the two ends are solid structures, the middle is hollow and the outer side is a decorative surface, the thickness of the two ends of the profile is between 40mm-45mm. When three cooling methods are adopted, namely natural cooling, strong wind on both sides and water spray cooling by tooling, the large surface in the middle of the profile will be wavy and deformed. To this end, a boss-shaped back rib is set in the center of the inner side of the profile along the length direction of the profile, and the boss height range is limited according to the wall thickness of the profile. It is possible to optimize the cross-sectional structure and solve the production problem of wave deformation after cooling while controlling the overall weight of the profile to be approximately the same as that before the back reinforcement is added.

[0051] In one embodiment, the profile size specifications and tolerances required by the customer are as follows: Figure 2 As shown, the solid thickness of the two ends of the profile is 43.28mm, and the middle wall thickness is 3.5mm, which is a difference of 12.3 times. When discharging, the temperature of the profile at the discharge port is between 510℃ and 520℃, and it needs to be cooled to normal temperature. In the quenching area of ​​the discharge port, before adding back reinforcement to optimize the cross-sectional structure of the profile, three cooling methods are adopted, namely natural cooling, strong wind on both sides, and water spray cooling by tooling. The discharge effect diagram recorded at the production site is shown below. Figure 3 , Figure 4 as well as Figure 5 As shown. It can be seen that after cooling in the above way, there will be waves on the middle large surface of the profile, and the overall cooling effect is: strong wind > tooling > natural. Therefore, by optimizing the cooling method, it is impossible to meet the production conditions and solve the problem of wave deformation after the profile is cooled. In addition, due to the production movement of the profile, the tooling water spray cannot stably act on the thick points on both sides.

[0052] After cooling, the wave deformation occurs at the upper and lower planes, with the outer side being the decorative surface, the inner side being hollow, and the two ends being solid as the connection stress positions. In order to solve the wave deformation problem after cooling, the cross-sectional structure of the profile is optimized by adding back ribs on the inner side of the profile to offset the wave deformation caused by uneven cooling. The back ribs are in the shape of bosses, and the height of the bosses is 2mm, and the width of the bosses is 15mm. The structure of the profile after adding back ribs is as follows: Figure 6 shown.

[0053] like Figure 7 As shown, after adding the back reinforcement, sampling is carried out and the plane gap is 0.2, which meets the profile size specifications and tolerances required by the customer. Figure 8 as well as Fig. 9 This is the framing diagram for the finished product, and the plane clearance meets the standards.

[0054] That is to say, after adding back ribs and optimizing the cross-sectional structure of the profile, strong air cooling is adopted, and the size and plane clearance of the profile after discharging and cooling meet the requirements of the drawing, so that production can be carried out smoothly.

[0055] The present invention also provides a device for adding back ribs to profiles to prevent cooling waves, which includes: a controller memory storing executable instructions; wherein the executable instructions can be run on the controller and implement the method for adding back ribs to profiles to prevent cooling waves.

[0056] The present invention also provides a computer-readable storage medium storing a computer program, which implements the method of adding back reinforcement to profiles to prevent cooling waves when the computer program is executed by a processor.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
